Michael Crabtree Treats Campers to Free Lunch ... Hope You Like Alligator!

San Francisco 49ers wide receiver Michael Crabtree treated 60 of his football campers to a cajun lunch ... and you know kids in Texas are different than most ... when they dine on fried alligator!

Crabtree held his second youth football camp at Southern Methodist University’s Gerald Ford Stadium this week in Dallas ... and took a bunch of the campers out to Pappadeaux Seafood Kitchen for a lunch that would not be recommended by the American Heart Association.

Crabtree footed the bill -- which we're told was at least a grand -- and in addition to the alligator, the kids dined on fish and grits, mozzarella sticks, gumbo, and shrimp salad ... among other things.

Sounds like the kids had a full day.
